Figure 1: Label-free detection of exosomes with nPLEX sensor. (a) Cancer cells secrete an abundance of exosomes through fusion of a multivesicular body (MVB) with the cellular plasma membrane.

“We present a CMOS-compatible double gate and label-free C-reactive protein (CRP) sensor, based on silicon on insulator (SOI) silicon nanowires arrays. We exploit a reference subtracted detection ...
